An independent holeless socket comprises: a shutter rotation device and a rotary conducting sheet mounting device. A cam (34) is mounted below a shutter (9), a rotary bracket (19) is mounted on a socket base (1), the rotary bracket (19) enables, by a rotary bracket shaft(16), the shutter (9) to open or close in a rotation manner, the rotary bracket shaft(16) is connected to the socket base (1), a spring (15) is mounted on the rotary bracket shaft(16), the shutter (9) is mounted on a shutter shaft (24), and the shutter shaft (24) is mounted on a shutter shaft bracket (11). When a plug is pressed against the shutter (9), the shutter (9) rotates downwards to expose holes (41), and after the plug is inserted, the cam (34) behind the shutter (9) pushes a rotary bracket tail to enable the rotary bracket tail to rotate outwards, and enables, according to the lever principle, rotary bracket heads of the electrified conducting sheets to rotate inwards to be fastened on the pins of the plug, thereby avoiding disconnected phenomenon. The appearance of the socket is a sealed cube and holes cannot be seen, so the socket is safer, disconnection is avoided, no spark flashes, the resistance is not increased, and the service life is prolonged.

A glycoprotein extracted from the fruiting body of Grifola frondosa is demonstrated to have antidiabetic, antihypertensive, antiobesity and antihyperlipidemic effects, and has great potential as an active component for pharmaceuticals, dietary supplements or health food preparations to treat and / or prevent the above diseases. This invention is to provide the glycoprotein and its preparation method.

The invention discloses a garden landscape floating bridge and a construction method thereof, and relates to he technical field of garden floating bridges. The garden landscape floating bridge comprises a bridge floor, the bottom face of the bridge floor is fixedly connected with first buoyant boxes, each two adjacent first buoyant boxes are connected with a string, and the outer sides of the twosides of the bridge floor are provided with limited columns inserted into the subaqueous soil; the top end of each limited column is 20 centimeters-40 centimeters higher than the bridge floor, the circumferential side faces, near the first buoyant boxes, of the limited columns are fixedly connected with limit blocks, one end of each limit block is located under the bridge floor, and the portion, between each two adjacent limited columns, along the bridge floor is fixedly connected with a fixing rod; the multiple limit columns along the bridge floor are connected with multiple second buoyant boxes located on the outer sides of the limited columns through safety nets, and the bottom face of each second buoyant box is fixedly connected with a fixed column inserted into the subaqueous soil. According to the garden landscape floating bridge and the construction method thereof, the buoyant boxes are arranged on the bottom face of the bridge floor, the limit columns and the safety nets are arranged on the outer sides of the two sides of the bridge floor to ensure people's safety, the entertainment sense of people walking on the floating bridge is improved, and dangerous things are avoided.
